The present study was conducted to determine the bacterial etiopathology of pulmonary infections in piglets, considering the increased incidence of mortality of piglets in Thrissur district, Kerala. Salmonella enterica serovar Choleraesuis (15), E.coli (5), Proteus sp.(3), Staphylococcus sp.(2) and Actinobacillussuis (1) were isolated from lungs collected from 25 porcine carcasses having respiratory lesions.No organisms could be isolated from two lungs which showed lesions. Collected lung samples showed lesions depicting circulatory, inflammatory, and ventilation disturbances or by combination of these changes. In most of the cases, the bronchial lymph nodes were swollen and congested, while the trachea showed presence of frothy or mucus exudates in lumen. Results of this study underscored the role played by Salmonella and E.coli in inducing respiratory infections, in addition to gastrointestinal disorders
